Heat Transfer
A superheated-stream generator without pressure vessels
The HGA-S-CX1300 system is an innovative high-temperature steam-generation device that instantly produces high-quality superheated steam at 1 atm pressure. Maximum steam temperatures of 1,300°C are available, with steam flowrates from less than 1 kg/h to more than 10 kg/h. The…
Energy Benchmarking
In today’s climate of increased energy prices and tightening environmental emissions requirements, petrochemicals producers around the world are continuing to focus on optimizing energy consumption at their facilities. Over the past few years, while energy prices have been increasing, petroleum…
Dow and Argonne National Laboratory collaborate on new battery materials
The Dow Chemical Company (Midland, Mich.; www.dow.com) and the U.S. Department of Energy's (DOE) Argonne National Laboratory (Argonne, Ill.; www.anl.gov) have signed a memorandum of understanding (MOU) for a multi-year research collaboration to jointly develop the next generation of materials…
A window into kettle reboiler secrets
Thermosiphon reboilers are the new standard in petroleum refineries and chemical plants. Nevertheless, approximately 50% of the world’s reboilers are kettles. In the realm of heat transfer, kettle reboilers have not been understood well. Last month, at ChemInnovations, however, Pete…
Steam generator operation and thermodynamics
A well-operated steam generator can save money. In a steam-driven turbine system, water is heated in the steam generator to produce high-temperature, high-pressure steam. Steam is then expanded in a turbine to produce electricity from a generator. Turbine steam is…
A new approach to maintaining tubular heat exchangers
At the 2nd Annual ChemInnovations Conference and Expo (Houston; September 13–15), Hemi-O Technologies LLC (Corpus Christi, Tex.; dixonengineering@gmail.com) introduced its patent-pending technology that enables external access to individual tubes in a heat exchanger while the exchanger is in service and…
Compact Reactors Boost Productivity
Velocys Inc. (Plain City, Ohio; www.velocys.com), a part of the Oxford Catalyst Group (Abingdon, U.K.; www.oxfordcatalysts.com), has been awarded the Kirkpatrick Award for Chemical Engineering Achievement from Chemical Engineering. The company’s winning technology features microchannel reactors for producing synthetic fuels.…
Heat transfer system cleaning
A well designed and operated heat-transfer-fluid system is a key feature of a safe, reliable and cost-effective heating design. However, problems can arise if the heat-transfer fluid becomes heavily degraded or the system is allowed to accumulate solids and other…
Eliminate downtime with a skid-mounted pair of PHEs
The GEASkid version of the NT Series is a plate heat exchanger (PHE) module with permanent standby function, comprising two completely independent PHEs designed to eliminate machine downtimes caused by maintenance. The GEASkid was developed to meet the safety requirements…
For cleaning applications, simply mix steam and water
The CSF Steam Water Mixer reliably and safely delivers hot water at the required temperature for cleaning or wash-down applications, especially those in the food and beverage industries. Made of stainless steel, the mixer can deliver water up to a…
